Subject [jira] Commented: (HBASE-3446) ProcessServerShutdown fails if META moves, orphaning lots of regions
Date Mon, 17 Jan 2011 19:27:43 GMT

    [ https://issues.apache.org/jira/browse/HBASE-3446?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12982812#action_12982812

stack commented on HBASE-3446:
------------------------------

OK, this is the one you figured.  Way back, there was some argument for why HTable could not
be used in place of HCM.  I'm not sure what it was now (or then really); but I just bought
it.

Is this worse than 0.89?  There does not seem to be any retry facility in the scan of meta
done in shutdown server handling there either? (Not that this makes the bug less severe...
I'm just trying to talk about whether it should hold up 0.90.0).

> I ran a rolling restart on a 5 node cluster with lots of regions, and afterwards had
LOTS of regions left orphaned. The issue appears to be that ProcessServerShutdown failed because
the server hosting META was restarted around the same time as another server was being processed
